The present invention relates to a 6-channel retroreflective metasurface antenna in azimuth direction. The six-channel retroreflective metasurface antenna in the azimuth direction according to the present invention is a lattice in which a plurality of unit cells in which a metal patch is designed on top of a metamaterial dielectric are arranged in a lattice, the unit spacing of each unit cell and the lattice between the lattice-arranged unit cells The operating elevation angle is determined according to the interval, and the operation is characterized in that it operates to reflect back the electric field incident in any one direction among six azimuth angles divided by 60° intervals. As described above, according to the present invention, the degree of freedom for the operating channel is high by controlling the operating elevation angle according to the unit spacing of unit cells arranged in a lattice and the lattice spacing between the unit cells and operating as a retroreflection in six channels in the azimuth direction. There is this.
